Coinbase joins Linux Foundation to launch x402 Foundation for HTTP 402 payments

On April 2, 2026, Coinbase Global (COIN) joined the Linux Foundation to formally establish the x402 Foundation, a nonprofit set up to steward an open-source protocol built around HTTP 402 "Payment Required". The X402 protocol turns the long-unused status code into a machine-readable payment flow that lets websites, APIs, and autonomous AI agents price and settle requests via digital wallets, including stablecoin-based settlement such as USDC.
